Holy balls Denon pumped up the prices on all models of AVR's another 100 bucks. A Denon x4700h originally had a MSRP of $1699 now has one of $2099. Good news for resale value for those who bought models early before price hikes and intend to resale later on!
It seems they increased prices by $100 for all models. The reason is probably that they believe people don't have good alternative anyway so the demand is strong and supply is short/disrupted. Which is not an unreasonable assumption. Even if you look at this forum, Denon (and some Marantz) are the only recommended AVP/AVR by @amirm (probably misleading since tested models had different DAC) in this price range.
